Objective To study the clinical features and treatment of 12 cases of lupus vulgaris.Methods A comprehensive study was performed on 12 patients with lupus vulgaris.The clinical and histopathological features,misdiagnosis,treatment and prognosis of this entity were analyzed.Results Of these patients,83.3% had a history of local trauma before the occurrence of lupus vulgaris.All the patients showed an early onset and long clinical course of lupus vulgaris,absence of obvious symptoms and variety in skin lesions.Lupus vulgaris was misdiagnosed at the first visit in all the patients.The final diagnosis was confirmed by histopathology,purified protein derivative (PPD) test,acid-fast staining,Mycobacterium tuberculosis culture,DNA sequencing,etc.Satisfactory outcomes were achieved in these patients after standard anti-tuberculosis treatment.Conclusions Lupus vulgaris is easy to be misdiagnosed and improperly treated due to its complicated clinical features.Clinicians should expand their knowledge about this entity,which can be diagnosed by histopathology and culture.

Non-invasive mechanical ventilation(NIV)is increasingly being used as a respiratory support technique in clinical practice.However,the pressure-related injuries should not be overlooked.In order to prevent local pressure injuries caused by NIV technology,a series of preventive measures have been adopted in clinical work.These measures include the use of dressings to provide pressure relief to the local skin.Currently,in clinical practice,when using preventive dressings,nurses need to cut them themselves based on the physiological structure of the patient's nose,forehead,or face.However,precise cutting can be challenging.If the dressing is cut too small,it may not provide adequate prevention,and if it's cut too large,it can cover too much skin,affecting the nurse's observation and the patient's comfort.Additionally,during NIV treatment,the preventive dressings used may become curled or displaced,requiring nurses to re-cut and replace them.This process inevitably leads to material wastage,increasing the cost of dressing use for patients.Moreover,the cutting tools used must meet infection control requirements,adding to the nursing workload and reducing the compliance of nurses in changing dressings.Our research team has designed a ready-made pressure injury prevention dressing component for use with NIV masks to prevent pressure injuries to the nasal and facial areas.It is precisely designed,flexible in composition,easy to use,and can provide multiple usage modes.It effectively combines emergency care with pressure relief measures,reducing the occurrence of pressure injuries to the patient's nasal and facial areas.This improves patient comfort and treatment compliance,facilitates technology-based nursing,and enhances clinical efficiency.It has significant clinical application value and has been granted a National Utility Model Patent(ZL 202020529121.6).
